Product details
Overview
BAT64-04T E6327 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as a series pair, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time, with typical forward voltage of 320 mV at 10 mA-used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT64-04T E6327 datasheet, BAT64-04T E6327 pinout, BAT64-04T E6327 application, or BAT64-04T E6327 equivalent, key selection criteria include its series dual-diode topology, low CT (4 pF @ 1 V), AEC-Q101 qualification, thermal resistance (RthJS ≤ 355 K/W), and RoHS-compliant lead-free packaging.
Technical Context
This dual-series Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports fast transient response in bidirectional clamping paths. Its low VF and sub-5 ns trr enable efficient high-frequency signal routing without significant conduction loss or switching delay.
The device operates across –55 °C to +150 °C junction temperature range and is thermally optimized for surface-mount PCB layouts with defined soldering-point thermal resistance (RthJS ≤ 355 K/W) under TS ≤ 61 °C ambient derating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping in 24 V automotive supply rails with 2× safety margin |
| Forward Current (IF) | 250 mA - sufficient for sensor bias current and low-power protection paths |
| Reverse Recovery Time (trr) | 5 ns - enables operation up to ~70 MHz signal edges without tail current distortion |
| Forward Voltage (VF) | 320 mV @ 10 mA - minimizes power loss and self-heating in always-on bias networks |
| Diode Capacitance (CT) | 4 pF @ 1 V, 1 MHz - preserves signal integrity in RF front-end and CAN bus termination |
| Junction Temp (Tj) | 150 °C - meets under-hood automotive thermal requirements per AEC-Q101 stress testing |

IC Role / Device Role / Timing Role: Series-connected Schottky pair acting as low-loss, bidirectional polarity guard. Use Value: Delivers <0.5 V total forward drop at 100 mA-preserving measurement accuracy while surviving 1000 V surge tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-04W | SOT323 package, lower RthJS (155 K/W), same series configuration and VF | Better thermal performance in space-constrained layouts; identical electrical specs | Preferred when board area allows smaller footprint and higher power density is needed |
| BAT54C | Common-cathode dual, not series; VF = 370 mV @ 10 mA; trr = 5 ns | Requires different PCB routing; unsuitable for center-tap clamping topologies | Select only if redesign supports common-cathode layout and dual independent clamping is acceptable |
Compared with BAR63-04W and BAT54C, BAT64-04T E6327 uniquely supports series dual-diode clamping in SOT23 with AEC-Q101 validation-making it optimal for automotive signal integrity where layout symmetry and qualification compliance are mandatory.

FAQ
What is the pin configuration of BAT64-04T E6327?
It is a 3-pin SOT23 device with Pin 1 = Anode of D1, Pin 2 = internal series node (Anode of D2 / Cathode of D1), and Pin 3 = Cathode of D2. The cathode marking is on Pin 3, consistent with JEDEC SOT23 orientation.
Is BAT64-04T E6327 suitable for 125 °C ambient operation?
Yes-its maximum junction temperature is 150 °C and thermal resistance (RthJS ≤ 355 K/W) allows safe operation at 125 °C ambient when power dissipation remains below 70 mW, verified per AEC-Q101 temperature cycling and HTOL test reports.
How does BAT64-04T E6327 differ from BAT64-04W?
BAT64-04T E6327 uses SOT23 packaging with RthJS ≤ 355 K/W and TS ≤ 61 °C rating, whereas BAT64-04W uses SOT323 with RthJS ≤ 155 K/W and TS ≤ 111 °C-making the -04W variant better suited for higher-power-density layouts.
Does this part require special ESD handling?
Yes-it is labeled ESD-sensitive per manufacturer documentation. Handling requires grounded workstations, ionized air, and static-dissipative packaging; failure to observe precautions may degrade reverse leakage or forward voltage consistency.
